Introducing 48V Telecom - Grade LiFePO4 Rack Battery
Basic Information
48V Telecom - Grade LiFePO4 Rack Battery refers to a 48-volt carrier-grade lithium iron phosphate rack battery, which is mainly used in telecommunications, solar energy, uninterruptible power supply (UPS) and other fields. This kind of battery has high stability and safety, and can meet the needs of long-term and high-load work

Key features:
A variety of capacities are available
There are various capacity specifications such as 100Ah, 200Ah, 300Ah, etc., which can be selected according to different application scenarios and needs, such as in solar systems, the appropriate capacity battery can be selected according to the scale of the system and energy storage needs12.

Communication protocols are available
Some products support RS485/RS232/Can-bus protocols, which facilitate communication and data interaction with other devices for remote monitoring and management, such as in solar energy systems, to understand the status and performance of batteries in real time1.

High number of cycles
Some batteries have 6,000 cycles, which means they can maintain a long service life during charging and discharging, reducing the cost of ownership

Modular design
The standard 19-inch rack mount is easy to install and maintain, and can flexibly combine multiple batteries according to actual needs to build energy storage systems of different sizes

Application scenarios
Solar energy system
As a key component of solar energy storage, it can store the electrical energy generated by solar panels and supply power to the load when the light is insufficient or at night, so as to realize the efficient use of energy

Telecom base stations
Provide stable power support for telecom base stations, ensure that base stations can still work normally when the mains power is interrupted, and ensure the continuity of communication.
Golf carts, electric scooters and other means of transportation
It can be used as a power source to provide stable power output for the vehicle, with high energy density and safety.

Home energy storage
It is used in household energy storage systems to store excess electrical energy, supply power to household electrical equipment, reduce dependence on the power grid, and achieve energy conservation and emission reduction

Features

B-LFP-483U rack batteries are made from a deep cycle prismatic LiFePO4 battery that combines proprietary architecture, circuitry, assembly methods and battery management systems (BMS) that are modular, lightweight and scalable for applications ranging from residential, commercial and industrial energy storage to telecom base station installations.
